We sleep under every blanket we recommend, for weeks, before we write a word about it

A blanket in regular nightly use is reasonable to wash every one to two weeks, similar to sheets. A couch throw used occasionally can usually stretch to once a month. Wool and down-alternative pieces tolerate washing less often and benefit from airing out between cycles instead.

Pilling happens when short, loose fibers rub against each other and tangle into little balls — it’s more common in synthetic fleece and sherpa than in tightly woven cotton or wool. Washing on a gentler cycle, turning the blanket inside out, and avoiding high heat in the dryer all slow it down, though some pilling is close to unavoidable over a blanket’s lifetime.

Not universally. They’re generally not recommended for infants, young children, or anyone who wouldn’t be able to remove the blanket on their own if needed. Adults with certain respiratory or circulatory conditions should also check with a doctor first. For most healthy adults, a weighted blanket in the commonly suggested range is considered low-risk, but “commonly suggested” isn’t the same as “right for you” — when in doubt, ask a physician.

A throw is a small accent blanket, usually 50 x 60 inches, meant for a couch or the foot of a bed rather than full coverage. A bedspread is sized to cover an entire mattress, often reaching the floor, and is typically the top layer in a made bed rather than something you’d sleep under directly.

Static builds up fastest in dry air and synthetic fibers rubbing against each other in the dryer. A dryer sheet or wool dryer balls during the drying cycle cuts most of it, and a room humidifier helps if the problem is really about winter air dryness rather than the blanket itself.

No — always check the care label first. Electric blankets should never go in a dryer, since heat and tumbling can damage the internal wiring. Weighted blankets often need a low, no-heat setting to avoid shifting the fill. Wool generally does better air-dried flat. Cotton and most synthetics tolerate a normal dryer cycle fine.

Generally, no — most heated blankets draw far less power than heating a whole room, since they’re warming one person rather than the air around them. Running one for a few hours nightly through a winter tends to add a modest amount to a monthly bill, usually far less than running a space heater for the same stretch of time.

A few reliable signs: the fill has gone flat or clumped in patches even after fluffing, the seams have started separating along a stress point like a corner, or the fabric has thinned enough to let light through when held up. Persistent pilling that a fabric shaver can’t keep up with is more of a texture issue than a durability one, so that alone isn’t always a reason to replace — but combined with the others, it’s usually a sign the blanket has reached the end of its useful life.
